Building on Arch Linux with 8Gb of ram, no swap. Can Acceptor.o require 8Gb to compile?

That's surprising to me -- it shouldn't, at least I have previously built in Ubuntu VMs with 1.5GB of RAM, but your compiler could have a bug.

I would recommend that you try debugging the usual way:

1) Use top, htop, atop, or ps to identify memory users on your system.

2) Try running just that one C++ compile under /usr/bin/time, as per the man page, it will print out memory usage in this format

           %Uuser %Ssystem %Eelapsed %PCPU (%Xtext+%Ddata %Mmax)k
           %Iinputs+%Ooutputs (%Fmajor+%Rminor)pagefaults %Wswaps

If the compile indeed consumes inordinate amounts of memory, please post more details here.

To even have a chance of reproducing, I'd need:
